Intro
After site selection, internal functional zoning becomes the core step to build a stable, low-PUE, compliant data center for global operators, enterprise self-built IDCs and edge computing hubs. Based on TIA-942, ISO/IEC 22237 international standards, we share universal partition schemes applicable to Southeast Asia, Middle East, Africa, Europe and America, covering thermal layout, power backup, fire protection and 24/7 monitoring zones, helping clients avoid layout defects and reduce long-term operation costs.
Main Body
1. Server Room: Standard Hot & Cold Aisle Isolation Layout
The IT white space is the core computing zone, adopting universal rack back-to-back arrangement to form independent cold aisles and hot aisles, the most recognized cooling layout worldwide.
Cold aisle: Front of server racks, supply cold air from CRAC/CRAH units; full cold aisle containment is recommended for 5–12kW per rack medium-density scenarios, widely used in small & medium IDCs in Southeast Asia and Africa.
Hot aisle: Back of racks, concentrate hot exhaust air back to cooling equipment; hot aisle containment is preferred for AI high-density racks above 15kW, fit for European & Middle Eastern large computing centers pursuing ultra-low PUE.
Global unified specification: Minimum aisle width 1.2m, raised floor height 600mm for underfloor air supply & cable routing; reserve 30% blank space for future server expansion.
Adaptation tip: For high-temperature & high-humidity regions like Malaysia, Indonesia, add air-tight partition panels to prevent hot air backflow and cut cooling power consumption by 25%+.
2. High & Low Voltage Power Distribution Room (Gray Space Core Zone)
Independent power zone separated from server room by fire walls, centralized layout of high-voltage switchgear, transformer, MDB, UPS mainframe and RPP remote power panels.
Partition rule: High-voltage incoming cabinet area at the outermost side, low-voltage distribution & UPS host near the battery room, shorten cable distance to lower power loss.
Global safety standard: Class A fire partition wall, independent exhaust ventilation, leak detection sensors, emergency power-off buttons outside the room.
Redundancy design applicable worldwide: Dual utility power input + N+1/2N UPS architecture, match grid instability conditions in Africa and Southeast Asia; reserved space for diesel generator linkage control cabinets.
3. Independent Battery Room (Mandatory Separate Zone)
Lithium or lead-acid battery packs cannot be placed together with UPS or servers; a fully enclosed independent battery compartment is a global compliance requirement.
Layout standards: Fire-resistant door, gas monitoring, temperature constant control 20–25℃, hydrogen exhaust ventilation system.
Spatial layout: Adjacent to low-voltage power room for short DC wiring; isolated from server & fire zones to avoid fire chain reaction.
Regional adaptation: Middle East high-temperature projects add air conditioning inside battery rooms to extend battery cycle life; tropical rain belt areas install waterproof floor & moisture-proof insulation.
4. Independent Fire Suppression Zone
Set up dedicated fire equipment storage & pipeline distribution area, separated from IT equipment area, equipped with global mainstream clean fire suppression systems: FM200 / IG541 Inergen gas fire extinguishing units.
Partition design: Fire zone closed with fire resistance 3-hour walls, independent pressure relief valves, smoke & temperature double sensors linked to DCIM monitoring.
Global compliance advantage: No water damage to servers, meets EU EN, US NFPA, Southeast Asia local data center fire codes; independent fire zone layout avoids system failure affecting all racks.
Layout logic: Fire pipeline main pipe routed along the corridor between power room and server room, easy maintenance without entering computing area.
5. NOC Network Operation & Monitoring Room
Centralized 24/7 management zone, physically isolated from server room, the command center of the whole data center.
Core equipment: Large monitoring video wall, DCIM integrated management system, access control host, environmental monitoring host, alarm intercom.
Layout advantage: Separated heat source, quiet operation environment for on-duty engineers; one-way access control to prevent irrelevant personnel entering IT area.
Global unified function: Real-time linkage monitoring of hot/cold aisle temperature, power load, battery voltage, fire signal, door access records, one-click alarm push for all abnormal faults.
Global Universal Layout Logic Summary
Heat zone (server room) in central area for convenient cooling delivery;
Power backup zones (power room + battery room) concentrated on one side for centralized energy management;
Fire zone as independent buffer between power area and server room for safety isolation;
NOC monitoring room set at the entrance of the whole facility for overall access & operation supervision.This zoning mode fits Tier 2/Tier 3/Tier 4 data centers, small edge modular rooms and enterprise private computer rooms, compatible with all mainstream overseas market construction standards.
